RRDcollect

RRDcollect is a daemon which polls certain files in /proc directory, gathering data and storing it inside RRDtool's database files.
Remember that this has to take place on your OpenWrt Router! But you can write to a remote filesystem (cifs.client or nfs.client) and execute RRDtool on that machine. If you wanted to. See charts.RRDtool for the charts.

RRD is the Acronym for Round Robin Database. RRD is a system to store and display time-series data (i.e. network bandwidth, machine-room temperature, server load average). It stores the data in a very compact way that will not expand over time, and it presents useful graphs by processing the data to enforce a certain data density. It can be used either via simple wrapper scripts (from shell or Perl) or via frontends that poll network devices and put friendly user interface on it.
This is version 1.0.x with cgilib-0.4, gd1.3 and libpng-1.0.9 linked into librrd.so. The library is much smaller compared to the 1.2.x version with separate dynamic linked libraries. This package contains a shared library, used by other programs.

Installation

Configuration

Examples

Start on boot

First create /etc/init.d/rrdcollect with the right content. Then
To enable/disable start on boot:/etc/init.d/rrdcollect enable this simply creates a symlink: /etc/rc.d/S??rrdcollect → /etc/init.d/umurmur/etc/init.d/rrdcollect disable this removes the symlink again
